Abstract

To solve the problem that a charging installation is essential for an EV, a LiB is heavy and a high cost, and its life is short due to a chemical battery, and it contains a heavy metal, and the EV is said as a pollution-free, but a lot of commercial power supplies is from a power of a hydrocarbon fuel.SOLUTION: The problem can be solved by performing an in-house power generation by a RFG in an EV vehicle. When a power is produced by oneself and consumed by oneself not only by being applied to the EV but also by installing a RFG+LiB to a general home and a business office, a problem on a blackout can be solved. On the earth, there are a pollution-free and unlimited energy, a gravity, and a magnetic force. Regarding to the gravity, a power is fetched out as a water force. The present invention is to fetch a power of a high voltage from a permanent magnet by using a natural law as a magnetic force of the permanent magnet, an electromagnetic induction, and a three-phase current. A generated power of the water force is calculated by a formula of 9.8×an effective head×water amount (m3/sec) ×a total efficiency. There is a formula of a construction factor having the maximum energy product (BH)max of the permanent magnet, a winding length, the number of poles, a speed (rpm) of a rotator, the total efficiency for the generation power of the magnetic force.SELECTED DRAWING: None

Description

In the present invention, an AC three-phase current of RFG having a permanent magnet as a rotor is supplied to an EV-equipped lithium-ion battery (hereinafter referred to as LiB).

A part of the AC power for the drive motor of the LiB mounted on the EV is used as the current of the RFG dynamic motor.

The RFG drive motor is turned on and off according to the remaining amount of electricity in the EV-equipped LiB.

The EV-equipped LiB, which is powered by the charging equipment from a commercial AC power supply, supplies power to the AC three-phase drive motor and the auxiliary DC power supply.

I have never heard of reports about installing a generator in an EV.

We started an experiment in which a solar cell was attached to the Prius PHV body. (2019.9.6. Yomiuri Shimbun)

Using permanent magnets, in 1832, the French Hippolite Pixie created the first hand-cranked RFG. He also invented a commutator that converts alternating current into direct current.

Gasoline engine generators, which are used as power sources for portable single-phase AC home appliances, do not use permanent magnets. By self-exciting current.

The current of the rotating armature type generator for the light of the bicycle, which fixes the permanent magnet and rotates the coil, is direct current.

RFG is the norm for high voltage generators. It is safer in terms of insulation and mechanically to rotate a field with a low DC voltage by using a heavy high voltage coil as a stator.

The high voltage and high current RFG has an iron core and therefore weighs more than 100 kg.

The cruising range of 1 EV is determined by the capacity of LiB.
2 EV consumes LiB power for both cooling and heating devices.
3 When the remaining amount of electricity in LiB decreases, it must be charged by the charging equipment, which takes time and effort.
About half of the price of 4 EV is LiB.
5 LiB accounts for several tens of percent of the EV vehicle weight and affects the cruising range.

An RFG is mounted on the EV to generate electricity according to the remaining amount of electricity in the LiB and supply power to the LiB.

1 RFG-equipped vehicles do not have to worry about the power consumption of heating and cooling.
Moreover, the travelable time depends on the life of the component parts such as LiB, and it is appropriate to set it to several years for the electronic parts.
2 The concept of cruising range is unnecessary for vehicles equipped with RFG.
3 The voltage current and DC auxiliary power supply required to start the drive motor of the RFG are the minimum required capacities of the mounted LiB, which drastically reduces the standard LiB capacity of the EV.
4 There is no gap between the charging equipment and charging.
5 EV prices will be discounted and their spread will be promoted.
